This is a broad project topic that will require adaptation depending on the interest of the student. All projects will be primarily experimental and involve learning technical fibre skills, particularly fibre splicing and component manufacturing.
Examples of research interests include:
- Designing and building high power, narrow linewidth fibre amplifiers.
- Stable narrow linewidth laser for atomic optics experiments at new wavelengths.
- Efficient second and possibly third harmonic generation of light in optical fibre system
This project will investigate practical improvements to fibre based Sagnac interferometers through both optical design and digital signal processing. The project will involve considerable practical work with optical fibre and fibre based light sources and detectors through the design and construction of a Sagnac interferometer. The other part of this project will involve signal processing through the programming of FPGAs and the required maths for improving the interferometer signal.
This project deals with Rubidium BECs in optical traps. We have previously investigated the tunneling behavior of trapped BECs through barriers theoretically. This project advances this research by observing the tunneling experimentally. Afterwards we want to put a trapped BEC between two barriers, which forms the atom-optic analog of a Fabry-Perot cavity, and study its behavior. This project is at the forefront of nonlinear quantum physics and has potential applications e.g. in the sensing of inertial or magnetic fields.
This project will focus on precision measurements of local gravity as well as magnetic and gravity gradients with an atom interferometer based on ultra-cold and condensed 87Rb. Through the use of novel interferometer techniques this apparatus will be used to both push the limits of current sensitivities as well as investigate fundemental physics problems.
We are looking for a PhD candidate who is eager to work on state-of-the-art cold and ultra-cold atom experiments and with prior experience in a physics lab.
In partnership with the group's ongoing effort to produce Australia's first optical clock, this project aims to produce a ultra-stable (1mHz linewidth) reference cavity. There will be two parrallel approaches to sovle this very demanding problem:
- The first will a novel design based on the standard linear cavity, as used in typical state-of-the-art optical clocks.
- The second is a unique approach attempting to minimize the size and robustness of current approaches through the development an ultra-stable fiber cavity.
This project aims to study dynamics and interaction in trapped 85Rb and 87Rb BEC mixtures. These systems are ideal candidates to model driven modulational and capillary instabilities. We have a well established experimental setup with a pipeline of experiments waiting to be built and run. This project is at the forefront of the highly competitive field of nonlinear quantum physics and we are looking for an engaging new team member to drive this project forward. A PhD in a relevant area of experimental physics and experience in working with mixed-species BEC would be the ideal ingredients to bring to this position.
This project is based on a precision measurements of inertial and magnetic fields and fundamental physics using our Rubidium BEC atom interferometer. This system has demonstrated the highest magnetic field gradient sensitivity to date and we are looking for a dedicated PostDoc to implement advanced next-generation measurement techniques such as advanced interferometer geometries, QND squeezing and large-momentum beam-splitter techniques. This will advance the performance of this instrument even further and enable a whole set of exciting new experiments.
We are looking for a person who is excited about fundamental physics and precision sensing in cold atoms and has a proven track record of working with cold or ultra-cold atoms and practical problem solving in the lab.
This project focuses on solving the real world problems which field deployable sensors such as absolute and relative accelerometers, magnetometers, and rotations sensors will face. Through theoretical modelling of possible environmental conditions and various operating platforms, optimized measurement techniques including sensor fusion, bandwidths, sensitivity, and, SWaP will be found. This information will be used to develop from the ground up a single axis quantum sensor which has been optimized for a specific platform in use for specific mapping capabilities.
We are currently running a program to build the first optical clock in Australia. The apparatus will be based on Strontium loaded into an optical lattice, high-finesse optical cavities and our existing frequency comb. We are looking for a PostDoc to drive our program forward and shape the future of precision timing in Australia. The ideal candidate has prior experience in precision spectroscopy and optical metrology, encompassing atomic clocks and high-finesse optical cavities.
